Landfill operators select daily cover materials based on factors such as effectiveness, cost, availability, and site conditions. They consider how well a material controls odors, litter, and pests, as well as how it responds to wind, rain, and temperature changes. Space efficiency is also important, since some covers take up less room than traditional soil.
Operators evaluate the ease of application, whether the material is reusable, and the equipment required for placement and removal. Regulatory approval is another critical factor, as only materials that meet environmental standards can be used. Operators may test different options in small areas to determine performance before implementing them across the site. Operators must balance operational efficiency, environmental protection, and budget considerations when making this choice.
